' vapors and gases laden with iodine products being sucked therefrom through a pipe 11' into a condenser 12 cooled by water or.air.' Here the iodine compounds are deposited as the result of the condensation and are col- 15 looted. Certain vapors not condensed are drawn from the condenser 12 through apipe v 13 to an absorber 14, where they are caused to rise through a body of water or an alkaline solution 15, where a further separation of the iodine compounds is obtained. The part 16 represents the pump for sucking the gas and vapors through this train of connections and the remaining gases after passing through the body of liquid in the absorber 14 are conducted by the pump through a pipe 17 to a receiver 18, where they again pass through Water to complete the condensation. It will be understood that the liquids condensed in the condenser 12 and absorbed in 80 the absorber 14 and the receiver 18 contain the valuable iodine compounds which it is sought to reci jtjger. I

WVhat I claim as new and desire to secure by Letters Patent is: as The process of producing iodine'compounds which consists in burning limestone in a kiln, extracting the-kiln gases therefrom and condensing the iodine compounds from said kiln gases. 40 Intestimony whereof I aifix my signature.
